I'm starting an accessory development project and want to make sure I'm purchasing the right thing. The example source code I have is based upon the Google ADK 2011 reference design. There is a 2012 reference design as well (http://developer.android.com/tools/adk/adk2.html). I've noticed the schematics for the Google reference ADK 2011 and the Mouser part number 782-A000069 are different, and the latter is listed as "Rev 3". Can anybody tell me the differences between these two designs? I could carefully go through the schematics but I'm afraid I might miss something important. Thx.

OK, thanks for that insight. By "old" I presume you mean the 2011 version and "new" the 2012 version. I purchased the iTead ADK, we'll see about compatibility with the existing SW. The schematics from their iMall site were illegible, but I was able to make it readable and it is the same as the Google reference design in major components and pinouts.
